Description

  The present invention relates to a biological information measuring apparatus which noninvasively detects various biological information from a finger of a living body.

  There are known various types of biological information measuring devices that measure predetermined physiological information (biological information) from a living body in order to know the state of the living body. For example, a sphygmograph measures pulse waves and the like of a living body, and for example, a pulse oximeter measures blood oxygen saturation and heart rate of a living body, and for example, a cardiac output meter The stroke volume is measured, and for example, a blood glucose meter measures the blood glucose level of a living body. There is a photoelectric method as one method of measuring biological information. The living body information measuring device using this photoelectric method measures predetermined living body information by, for example, emitting and receiving light on the finger of a living body. In such a biological information measuring device, when water is applied, water may infiltrate into the inside, which may cause a failure of the device. Therefore, the biological information measuring device is required to be waterproof.

  For example, Patent Document 1 discloses a waterproof probe provided with a light emitting portion and a light receiving sensor and covered with a covering material. And in this patent document 1, an apparatus main body separated from a probe and connected by a cable calculates a numerical index based on data obtained by this probe.

  Also, for example, Patent Document 2 includes a first fixing portion in which a portion of the measuring portion is disposed, and a second fixing portion in which the other portion of the measuring portion is disposed. A living body information measuring apparatus is disclosed in which a first fixing portion and a second fixing portion are rotatably connected while being electrically connected to another portion. Then, by holding the finger in the finger placement portion formed between the first fixing portion and the second fixing portion, a part of the measuring portion disposed in the first fixing portion and the second portion The biological information is measured with the other part of the measurement part disposed in the fixed part.

  However, in Patent Document 1, although the probe is supposed to be waterproofed covered with a covering material, the device main body for calculating the numerical index is separated from the probe, and the entire device is waterproof. It is not. Therefore, when water is applied to the main body of the apparatus, the water intrudes into the inside of the main body of the apparatus and causes the failure of the main body of the apparatus.

  In Patent Document 2, when water is applied to the first fixing portion or the second fixing portion because water does not have waterproof property, water intrudes into the inside to cause a failure.

  Further, in this case, it is conceivable to cover the first fixing portion and the second fixing portion with a covering material as in the probe of Patent Document 1 to make the entire device waterproof. However, the connection part between the part of the measuring part disposed in the first fixing part and the other part of the measuring part disposed in the second fixing part must also be covered with the covering material. Moreover, at that time, since the first fixing portion and the second fixing portion rotate at the time of measurement, if the connection portion is covered with the covering material as it is, the first fixing portion and the second fixing portion are smoothly rotated. You may not be able to move. Therefore, it is difficult to apply the covering material of patent document 1 to the 1st fixing | fixed part and 2nd fixing | fixed part of patent document 2 as it is.
